Dedicated Heat Pump Circuit in Lake Forest Park, WA 98155: The Electrical Side of a Mini-Split Install

Stephanie, a returning Product Air customer on the 31st Drive NE corridor in Lake Forest Park, had a new Mitsubishi heat pump system going in with head units planned for each bedroom. The new heat pump brings its own electrical needs, and this job was the part of the project most homeowners never see: getting power safely and correctly from the panel to the new outdoor unit before anyone thinks about airflow or temperature at all.

The House in Lake Forest Park

Stephanie’s home is a 4,900-square-foot, two-story single-family house built in 2019, with four bedrooms. It’s a newer build, so the electrical work here had nothing to do with an outdated panel. The heat pump installation is written up as a separate case, which is why this job stands on its own as an electrical project. The circuit, breaker, and disconnect were scoped and invoiced apart from the equipment.

Why Stephanie Called Product Air

Stephanie called on May 5, 2026, and Alex West's crew was on site eight days later, on May 13, to handle the electrical portion of a larger heat pump equipment installation. When the crew arrived, the homeowner greeted them, showed them her electrical panel, and let them know where she'd be in the home if they needed anything, then let them get to work.

The equipment decision itself, why a multi-zone system with head units in each bedroom was the right call for this home, was made on the sales side of the job before Alex's electrical crew was ever on site. That's where the record for this particular visit stops. Alex wasn't part of that conversation, and the job record on file doesn't have it either. What is documented is the electrical scope his crew was there to execute.

Do Ductless Heat Pump Systems Need Their Own Electrical Circuit?

Yes. A ductless or mini-split heat pump's outdoor condensing unit needs a dedicated circuit sized to the equipment, run from the home's main electrical panel to a disconnect at the outdoor unit. It isn't something that gets tapped off an existing circuit already carrying other loads. That's true whether the home is getting one indoor head unit or several, and it's typically the first thing that has to happen before the heat pump installation itself can be completed and started up.

Stephanie's Panel and the New Mitsubishi System

The outdoor unit of the new Mitsubishi system is rated for 25 amps. The circuit was run in 8 AWG wire to a disconnect rated for 30 amps. The scope was a new breaker in the main panel and a dedicated run of up to 45 feet from the panel to the disconnect.

What Product Air Did: Alex's Electrical Work

Alex handled the electrical scope for Stephanie's job. The invoiced work was a new circuit breaker installed in the home's main electrical panel and a new dedicated electrical run from that panel out to the outdoor heat pump unit's disconnect, a run of up to 45 feet. An electrical permit was required for the work, which is standard for a new circuit of this kind. Alongside the circuit work, the job included new Mitsubishi communicating wireless thermostats for the system, one included with the job and two more added.

Alex described the job itself as routine electrical work, nothing non-standard about it. That's worth taking at face value rather than dressing it up: not every job in this series involves an unusual complication, and a straightforward, correctly permitted circuit run is exactly what this kind of installation is supposed to look like when nothing goes sideways.

What a Dedicated Circuit Protects Against

A shared or undersized circuit is not a minor shortcut. An outdoor heat pump unit pulls a steady, specific load when it starts and runs, and a circuit that's also carrying other household loads can trip under that draw or, worse, run hot without tripping at all. A dedicated circuit sized and permitted for the equipment removes that risk at the source, and it's also what most manufacturers expect to see behind their equipment for the warranty to apply cleanly. This is why the electrical scope gets scheduled and inspected before the heat pump startup, not after.

What Was Installed

The electrical side was simple: make sure the new system had the right power in place before startup.

The Timeline

Stephanie called on May 5, 2026. Alex's crew completed the electrical scope on May 13, the same day work began.

The Real Number

The invoiced total for the electrical scope was $4,240.67, which reflects a 3 percent cash discount of $118.80 for paying by ACH transfer rather than card. Electrical work like a dedicated circuit run does not carry a utility rebate in most cases, and none applied here. The only reduction on the invoice was that cash-payment discount.

For homeowners who would rather spread this kind of cost out instead of paying it in one transfer, we work with GreenSky and Service Finance Company, LLC, and most applications get a decision in minutes. Financing is subject to credit approval.

Warranty

Product Air Heating, Cooling, and Electric provides a five-year labor warranty on its installations.

What Stephanie Got From the Electrical Work

With the dedicated circuit and disconnect in place and permitted, the home now has properly sized, code-compliant power for its new heat pump system, and each zone controlled by its own head unit gives better climate control room by room than a single whole-house system would. Stephanie thanked the crew for their work when it was done.

Frequently Asked Questions

Does a heat pump need a dedicated electrical circuit?

Yes. The outdoor condensing unit needs its own circuit, sized for the equipment, run from the main panel to a disconnect at the unit. It can't share a circuit with other household loads.

Is an electrical permit required for a new heat pump circuit in Washington?

Yes, a new dedicated circuit of this kind requires an electrical permit. In Lake Forest Park, that permit is purchased through Washington State L&I rather than the city, since Lake Forest Park doesn't run its own electrical permitting program.

What is a communicating wireless thermostat?

A communicating thermostat exchanges data continuously with the heat pump system rather than just sending a basic on and off signal, which allows more precise, zone-specific control. Mitsubishi's systems are designed around this kind of thermostat for accurate per-zone performance.

How far can an electrical circuit run from the panel to an outdoor unit?

It depends on the home's layout and the equipment's electrical requirements. This job's run was up to 45 feet from the panel to the disconnect. Longer runs can mean additional wire and labor costs, which is why it's usually priced as its own line item separate from the heat pump equipment itself.

Do utility rebates cover heat-pump-related electrical work?

Generally not. Utility rebates are tied to the efficiency of the equipment being installed, so the electrical-only scope of a job (a dedicated circuit run, a panel change, or a disconnect) is not itself eligible even when the heat pump it serves might be. On this project only the electrical work was invoiced, and it carried no rebate, just a 3 percent cash-payment discount.

How long does a dedicated circuit installation like this usually take?

For a job like Stephanie's, with a new breaker and a run of up to 45 feet, the electrical work was completed the same day it started. Longer runs, older panels, or a panel that needs its own upgrade first can add time.

Does an older home need its panel upgraded before a heat pump circuit can be added?

Sometimes. It depends on how much open capacity the existing panel has. A licensed electrician checks the panel's rated capacity and existing load before adding a new circuit, and if there isn't room, the panel itself becomes part of the job. Stephanie’s 2019 build didn’t need a panel upgrade.

Key Takeaways

• A new ductless heat pump system needs its own dedicated, permitted electrical circuit from the panel to the outdoor unit. It can't share an existing circuit.
• This job's run was up to 45 feet and required a Washington State L&I electrical permit, since Lake Forest Park doesn't issue its own.
• The electrical scope, $4,240.67, was billed and permitted separately from the heat pump equipment sale.
• Electrical scope, such as a dedicated circuit run, does not carry a utility rebate in most cases. The only reduction here was a 3 percent cash-payment discount.
• Budgeting for panel and circuit work as its own line item, rather than assuming it's bundled into a heat pump quote, avoids surprises on jobs like this one.

Power First, Comfort Second

Every mini-split or heat pump install has an electrical job hiding inside it, and it's the part that has to be right before anything else about the system matters. Stephanie's new circuit was straightforward work, done correctly and in the way it should be, which is exactly what this kind of job is supposed to look like.

If you're planning a heat pump or mini-split install and aren't sure whether your panel has room for it, that's worth a look before equipment gets ordered. See our reviews on Google or reach out to get the electrical side scoped alongside your heat pump quote.
